Cromar Exterior Water Seal is a clear, high performance, waterproof treatment for exterior porous surfaces such as brickwork, asbestos and cement. Its water repellent formula makes it ideal for  exterior surfaces.

Coverage will depend on the porosity of the substrate. Guideline coverage is 2-4m²/litre/coat.

Exterior Water Seal is for use on brickwork, concrete, stone, paving, asbestos and cement. It can also be used to repel water on exterior wood that has previously been treated with a preservative.

 

 

 

APPLICATION

All surfaces to be treated should be dry, clean and free from dirt, dust, oil, grease and organic growth. Surfaces may be washed down with clean water but detergents of soap solutions should not be used. Do not apply for 2/3 days after rain. Defective mortar should be removed and replaced with new. The product will not be effective on materials that are unsuitable for exterior use. Exterior Water Seal should not come into contact with windows or other glazed areas, which should be masked to prevent splashes. In such instances contaminated areas should be wiped immediately with White Spirit.

Exterior Water Seal is ready to use and should not be diluted. Shake container before use. The material should be applied liberally by soft bristled brush or low-pressure airless equipment avoiding mist forming by using a course spray nozzle. On masonry a single application is normally all that is required but on porous surfaces a second application may be applied as soon as the first coat has dried. On wood, two coats are also required. Treatment should start at the top and work down.

Cannot be over-painted therefore it should be used as a final application only, as it may affect the adhesion of subsequent coatings.
